changing ip and host name of running vertica cluster. Moved cluster to a new site
I am currently running a 3 node cluster with restart option as k-safe mode. Actually all three nodes were hosted in 3 different virtual machines.
As per the movement of servers to new site, I had to reconfigure the ips to new ip address and also the new host name. I remember, sometime back I had used the re_ip option with admintool ( example : admintool - t re_ip -f re_map.txt ) and it changed the required file automatically and the servers also restarted.
I created a re_map.txt file
$admintools -t list_all_nodes
$admintools -t re_ip -f re_map.txt
Parsing Mapping file
Host : Unreachable .......
Note: I have no clue why am I getting this error. I believe this is udp or tcp connection , right? Can I check the port for making sure the connection reaching to the end point?
In fact, I tried to update the admintool.conf file with the new ip address but that didn't work. When I started the DB on server its giving some synchronization error.
I am not sure how to change the required file for manual update of the networking change.
Need some help. Please advise.
